My friend, all these other sources are meaningless, why aren't...

My friend, all these other sources are meaningless, why aren't you using the most recent given to you, by ACTUAL extraction? such as : 1900-3800mg/L?
the ones I MENTIONED, why do you keep piling here, with old tables and concentrations, and portend that to be good DD? the good cop bad cop runs rampant here. Unbelievable.

These good guy/bad guy bears are interesting, to say the least, oh and entertaining.

As to @bombersmadd I will repeat, the numbers you mentioned are just benchmarks, and numbers to work from, never were they claimed to be the actual absolute concentration. They mentioned those numbers from concentrations they either had elsewhere, or simple benchmarks to work out concentration amount.
